Caffeic acid phenethyl ester (CAPE) could ameliorate myocardial ischemia/reperfusion injury (MIRI) by various mechanisms, but there hadn't been any reports on that CAPE could regulate silent information regulator 1 (SIRT1) and endothelial nitric oxide synthase (eNOS) to exert cardioprotective effect. The present study aimed to investigate the cardioprotective potential of caffeic acid o-nitro phenethyl ester (CAPE-oNO2) on MIRI and the possible mechanism based on the positive control of CAPE. The SD rats were subjected to left coronary artery ischemia /reperfusion (IR) and the H9c2 cell cultured in hypoxia/reoxygenation (HR) to induce the MIRI model...

BACKGROUND: Serum vitamin B12 levels have been proposed as one of the survival prediction factors, although no survival analysis in metastatic cancer patients has been conducted yet. This study examined whether serum vitamin B12 levels could be a prognostic factor in metastatic cancer patients. METHODS: Data from a retrospective chart review were used to perform Kaplan-Meier and multivariate analyses of the Cox proportional hazards. Subgroup analysis was performed on patients without a liver lesion (hepatocellular carcinoma or liver metastasis)...

Context: It is unclear whether relative elevations in androgens or irregular menses (IM) are associated with greater cardiometabolic risk among women who are already overweight and glucose intolerant. Research Design and Methods: We conducted a secondary analysis of Diabetes Prevention Program (DPP) and the DPP Outcomes Study (DPPOS). Participants included women with sex hormone measurements who did not use exogenous estrogen (n=1422). We examined whether free androgen index (FAI) or IM were associated with diabetes risk during the DPP/DPPOS or with coronary artery calcification (CAC) at DPPOS year 10...

Purpose Chemoradiation with cisplatin 100 mg/m2 given once every 3 weeks is the standard of care in locally advanced head and neck squamous cell cancer (LAHNSCC). Increasingly, low-dose once-a-week cisplatin is substituted because of perceived lower toxicity and convenience. However, there is no level 1 evidence of comparable efficacy to cisplatin once every 3 weeks. Patients and Methods In this phase III randomized trial, we assessed the noninferiority of cisplatin 30 mg/m2 given once a week compared with cisplatin 100 mg/m2 given once every 3 weeks, both administered concurrently with curative intent radiotherapy in patients with LAHNSCC...

OBJECTIVES: To determine whether clinically relevant portal hypertension (CRPH) influences outcome and whether it may serve as a prognostic marker in patients treated with transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). METHODS: One hundred and forty-seven patients underwent conventional TACE as a first-line treatment for a single HCC. CRPH was graded as 0, 1, or 2. The influence of CRPH, together with other factors, on local tumour progression (LTP) and overall survival (OS) were analysed using Cox proportional hazards regression...

PURPOSE: Since the widespread implementation of adding palbociclib to endocrine therapy in clinical practice, myelosuppression is becoming increasingly recognized as a toxicity that may lead to dose modification. We aimed to characterize toxicities observed with palbociclib resulting in dose modifications and prescriber preferences in modifying palbociclib dosage in response to treatment-related toxicities outside the context of a clinical trial. METHODS: We conducted a single institution, retrospective study of treatment-related adverse events (AEs) resulting in modifications in dose and schedule and the methods by which dose modifications occurred in patients with advanced hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer receiving palbociclib and endocrine therapy...

BACKGROUND: Extreme telomere length has been previously reported to be associated with increased risk of gastric cancer. However, evidence from prospective studies on a relative large sample size with long-term follow-up to further corroborate previous study findings is meager. METHODS: The association between peripheral blood leukocyte telomere length and risk of gastric adenocarcinoma was prospectively examined in a cohort of 26,540 middle-aged or older Chinese nested in the Singapore Chinese Health Study...

Background and Aims: Haemodynamic responses to laryngoscopy and endotracheal intubation and their hazards are well documented. The purpose of the study was to compare the effects of laryngoscopy and intubation on cardiovascular responses when the appropriate moment for intubation was directed by either clinical judgment or train-of-four assessment. Methods: A total of 68 patients, posted for laparoscopic cholecystectomy, were randomised into two groups. In Group M patients, the trachea was intubated after train of four counts became zero in adductor pollicis muscle, whereas in Group C patients, the trachea was intubated after the clinical judgment of jaw muscle relaxation...

It has been long assumed that post-mitotic neurons only utilize the error-prone non-homologous end joining (NHEJ) pathway to repair double strand breaks (DSBs) associated with oxidative damage to DNA, given the inability of non-replicating neuronal DNA to utilize a sister chromatid template in the less error-prone homologous recombination (HR) repair pathway. However, we and others recently have found that active transcription triggers a replication-independent recombinational repair mechanism in the G0/G1 phase of the cell cycle...

OBJECTIVE: To study the risk of a second malignant neoplasm (SMN) and mortality in patients with rheumatoid arthritis (RA) with a history of a primary cancer diagnosis and treated with biological disease-modifying antirheumatic drugs (bDMARD). METHODS: Among patients with RA (n=15 286) registered in the DANBIO Register during 2000-2011, 1678 had a primary cancer according to the Danish Cancer Registry. HRs for SMN and death were calculated. RESULTS: During follow-up there were 279 patients with RA contributing person-years to the bDMARDs use before their primary cancer diagnosis, 220 to the only after, 92 to the both before and after, while 1203 patients with RA contributed to the non-use strata...

Cystinosis is an orphan disease caused by a genetic mutation that leads to deposition of cystine crystals in many organs including cornea. Ophthalmic manifestation of the disease can be treated with hourly instillation of cysteamine eye drops. The hourly eye drop instillation is tedious to the patients leading to poor compliance and additionally, significant degradation of the drug occurs within one week of opening the bottle, which further complicates this delivery approach. This paper focuses on designing a contact lens to treat the disease with improved efficacy compared to eye drops, and also exploring safety of the drug eluding contact lens in an animal model...

OBJECTIVE: Early data suggest that FEVAR is feasible but may have higher morbidity and unclear durability compared to open surgical repair (OSR) of complex abdominal aortic aneurysms (CAAA). We compared the early experience following elective FEVAR to traditional OSR of CAAA in a high-volume open aortic center. METHODS: All patients undergoing FEVAR and OSR for elective CAAA from 1/2010-7/2015 were identified. Univariate, multivariable logistic, and Cox hazards modeling were used to compare perioperative and intermediate outcomes...

The optimal viral load threshold to initiate pre-emptive cytomegalovirus (CMV) therapy in hematopoietic cell transplant (HCT) recipients remains to be defined. In an effort to address this question we conducted a retrospective study of 174 allogeneic HCT recipients transplanted at a single center between August 2012 and April 2016. During this period, pre-emptive therapy started at the discretion of the treating clinician. 109 (63%) patients developed CMV viremia. Median time to reactivation was 17 (IQR, 7-30) days post-HCT...

BACKGROUND: Multimodal therapy is the standard treatment for pediatric rhabdomyosarcoma, but for adolescents and young adults (AYAs: ages 15-39) and older adults with rhabdomyosarcoma, the use of adjuvant therapy is variable, and survival is greatly decreased compared with younger patients. METHODS: All patients with rhabdomyosarcoma who had a curative operative were identified from the 1998-2012 National Cancer Database. Regression analyses identified independent factors relating to receipt of multimodal therapy (resection + chemotherapy + radiation) and the influence of multimodal therapy on 5-year overall survival...
